Duplicate of PROTEIN SYNTHESIS

which of the following is a nucleotide of DNA

• ribose+ phosphate+thymine
• ribose+phosphate+uracil
• deoxyribose+phosphate+uracil
• deoxyribose+phosphate+cytosine

because of base pairing in DNA the percentage of

• adenine is equal to guanine
• pyrimidines is equal to purines
• purines is larger than pyrimidines
• cytosine is greater than guanine

in eukaryotes, DNA

• located in the nucleus
• float around in cytoplasm
• located in the ribosome
• is circular

DNA is copied during a process called

• replication
• translation
• transcription
• transformation

DNA replication results in 2 DNA molecules

• each with 2 new strands
• one with 2 new strands and one with 2 old  strands
• each with one new and one old
• each with 2 original strands

The DNA strand with ATTCGA will replicate bases to produce a new DNA strand with

• TAAGCT
• AGCCTTA
• ATTCGA
• TTAACCA

RNA contains the sugar

• ribose
• deoxyribose
• glucose
• lactose

Unlike DNA, RNA contains

• adenine
• uracil
• phosphate
• thymine

Which of the following are found in both DNA and RNA

• ribose, phosphate, adenine
• deoxyribose, phosphate, guanine
• phosphate, guanine, cytosine
• phosphate, guanine, thymine

How many types of RNA are there?

• 1
• 2
